What are the 5 sections of the pelvis?

A spade-shaped bone that is formed by the fusion of 5 originally separate sacral vertebrae. Coccyx (also called the tailbone)….These are:

  • Ilium. This is the broad, flaring portion of the pelvis.
  • Pubis. This is the lower, front part of the pelvis.
  • Ischium. This is the part of the pelvis that forms the hip joint.

What are the 3 main spinal regions?

The spine has three normal curves: cervical, thoracic and lumbar. There are seven cervical vertebrae in the neck, 12 thoracic vertebrae in the torso and five lumbar vertebrae in the lower back.

Is the coccyx part of the sacral region?

The sacral region (sacrum) is at the bottom of the spine and lies between the fifth segment of the lumbar spine (L5) and the coccyx (tailbone). The sacrum is a triangular-shaped bone and consists of five segments (S1-S5) that are fused together.

What is the thoracic spine?

The thoracic spine is located in the upper and middle part of the back. Twelve vertebrae are located in the thoracic spine and are numbered T-1 to T-12. Each number corresponds with the nerves in that section of the spinal cord: T-1 through T-5 nerves affect muscles, upper chest, mid-back and abdominal muscles.

What is the sacral region?

The sacral spine (sacrum) is located below the lumbar spine and above the tailbone, which is known as the coccyx. Five bones that are fused together make up the triangle-shaped sacrum, and these bones are numbered S-1 to S-5. Each number corresponds with the nerves in that section of the spinal cord.

What is the difference between coccyx and sacrum?

The coccyx, commonly known as the tailbone, is below the sacrum. Individually, the sacrum and coccyx are composed of smaller bones that fuse (grow into a solid bone mass) together by age 30. The sacrum is made up of 5 fused vertebrae (S1-S5) and 3 to 5 small bones fuse creating the coccyx.

What is the sacral spine?

What are the 4 regions of the spine?

Typically, the spine is divided into four main regions: cervical, thoracic, lumbar and sacral. Each region has specific characteristics and functions.

What is a thoracic region?

Your thoracic spine is the middle section of your spine. It starts at the base of your neck and ends at the bottom of your ribs. It consists of 12 vertebrae. Your thoracic spine is especially rigid and stable, making it the least common area of injury along your spine.

What region is the coccyx in?

The coccyx is a triangular arrangement of bone that makes up the very bottom portion of the spine below the sacrum. It represents a vestigial tail, hence the common term tailbone.
